Degradation Process of Coated Tinplate by Phase Space Reconstruction Theory

The degradation process of organosol coated tinplate in beverage was investigated by electrochemical noise （EN） technique combined with morphology characterization. EN data were analyzed using phase space recon- struction theory. With the correlation dimensions obtained from the phase space reconstr...

Summary:The degradation process of organosol coated tinplate in beverage was investigated by electrochemical noise （EN） technique combined with morphology characterization. EN data were analyzed using phase space recon- struction theory. With the correlation dimensions obtained from the phase space reconstruction, the chaotic behavior of EN was quantitatively evaluated. The results show that both electrochemical potential noise （EPN） and electrochemi- cal current noise （ECN） have chaotic properties. The correlation dimensions of EPN increase with corrosion extent, while those of ECN seem nearly unchanged. The increased correlation dimensions of EPN during the degradation process are associated with the increased susceptibility to local corrosion.
